Onion Browser is the original free and open-source Tor-powered web browser for iOS. Onion Browser helps you access the internet with more safety and privacy, and no extra cost to you. “The best Tor-related offering on iOS right now is Onion Browser” - The Daily Dot, October 14, 2015. Featured in: The New York Times, The Guardian, Salon, TechCrunch, Gizmodo, Boing Boing, Lifehacker, Macworld, The Daily Dot, & others. FEATURES: • Browse the internet over Tor: - Protect your privacy from website tracking - Secure your traffic from insecure wireless networks and ISPs - Access .onion sites that are only accessible over Tor. • Fight online tracking: block scripts and automatically clear cookies and tabs, based on your preferences. • And more privacy-enhancing features! DISCLAIMERS: - Web browsing is much slower than through a normal web browser or a VPN because your traffic is encrypted and relayed through the Tor network. - Onion Browser might not work on networks with advanced network restrictions. If the app does not connect, try using bridges (or a different type of bridge), force-quit, and then restart the app. - Use of Onion Browser is at your own risk; remember that sensitive data does not always belong on a mobile device. ** Onion Browser is free and open-source software.

Verdict
The clearest difference is rating: Onion Browser at 3.2 against CVE Alert's 1.0. Onion Browser also leads on review sentiment (41% vs 0%) and ratings volume (2.1K vs 1). CVE Alert's advantage is in-app purchases (none vs 3) and update cadence (fortnightly vs monthly). On price, ads, device support and iOS requirement there is nothing between them.

Onion Browser ships an update monthly, CVE Alert fortnightly. The most recent releases landed on October 14, 2026 and October 5, 2026 respectively.
